Alexander. Alexander of Hales, the Franciscan theologian and
philosopher, Doctor Irregragabilis, was one of the greatest of the
scholastics. He was born at Hales, or Hailles, in Gloucestershire towards
the end of the twelfth century, and died at Paris at the convent of his
Order in 1245. His principal work is the Summa Uniuersae
Theologiae, begun about the year 1231, and left unfinished. It has
several times been published: Venice, 1475, 1576; Nuremburg, 1481, 1502;
Pavia, 1481; Cologne, 1622. A critical edition, which is much needed, has
been promised by the Quaracchi editors of the works of S. Bonaventura.
